Abstract
A connection means for coupling two components (7), particularly precast concrete parts (6), comprises a pin (2) which supports at least one axially fixed spring element (3) which counteracts the tensile force acting on the pin (2) when the connecting means (1) is in a mounted state.
Description
Connection means for coupling two components The invention relates to a connection means for coupling two components, in particular precast concrete parts, having a bolt, and components.
In the sector of precast concrete part construction, components such as precast concrete parts are used and, in particular, concrete slabs which, on their abutting edges, display grooves and which, for connecting the precast concrete parts, are packed with concrete and, for absorbing tensile forces, are additionally equipped with anchors, screws, metal loops or brackets, are used for building support structures, facades, walls and/or ceilings. All these connection elements are inserted into the precast concrete parts already during production, wherein both the precast concrete parts to be connected have to be equipped with these connection elements.
For the connection of two components, it is known, for example from DE 10 2010 030 281 Al, to use bolts which are provided with a thread, for example, and are screwed directly into the component or into an anchor which is fastened in the component. When using such a bolt, it is not possible to couple two components so that they abut.
There always remains a gap in which a tool can engage on the bolt for turning the same.
The invention is based on the object of providing a connection means of the type mentioned at the outset which, while offering simple handling, ensures a connection of two components and transmits comparatively large forces.
According to the invention, the object is achieved by the features of the independent claims.
The dependent claims represent advantageous embodiments of the invention.
A connection means for coupling two components, in particular precast concrete parts, comprises a bolt which carries at least one axially fixed spring element which, in the mounted state of the connection means, counteracts an extraction force acting on the bolt.
The design of the connection means may be comparatively multifaceted, but always comprises at least one spring element which is effective in the axial direction and which is either placed onto the bolt, i.e connected to said bolt in a force-fitting and/or form-fitting manner, or is integrally produced with the bolts. The bolt may be inserted into a prefabricated boring by way of a blow of a hammer, in the manner of a nail provided with a resilient barb or a resilient tongue, for fastening, for example a metal component on a concrete element, in particular a precast concrete part. To this end, the bolt, on its one end, for example, displays a head which is enlarged in relation to the remaining profile, and, on the end lying opposite the head, displays a phase or a cross-sectional tapering which also carries the spring element, for example. However, a cylindrical bolt in which the spring element is disposed or configured so as to extend across the entire circumference, or so as to be a type of barb, for example, may also be used.
Of course, the use of the described connection means is possible not only in the case of a component of concrete, but also in conjunction with components of wood, plastic, and similar materials, without departing from the scope of the invention.
In an embodiment, the bolt carries at least two spring elements which are effective in opposite directions. The spring elements which are configured as spring arms or spring disks, for example, are jammed in corresponding openings of the components to be connected to one another, wherein the jamming effect increases in the case of an acting extraction force. When being inserted into the opening, the spring elements are squeezed together in order to reduce their usable width, wherein the direction for joining the connection means and the components is opposed to the direction of the extraction force. When the bolts and the spring elements are made from a correspondingly strong material, comparatively large forces can be transmitted without the coupling of the components connected to one another by the connection means being neutralized or the used connection means being damaged.
The spring element is preferably configured as a toothed spring disk which is insertable in a pre-tensioned manner into a boring of the component. The toothed spring disk expediently displays an elliptical, oval, or polygonal outer contour. Saucer-shaped toothed spring disks are available as cost-effective standardized products, and a cylindrical boring having a diameter which is made to be somewhat smaller than the outer diameter of the toothed disk can be readily produced. However, it is also conceivable for the toothed spring disk to be made having an outer contour which enables, for example, an increase in the jamming effect, an employment in an opening which differs from a cylindrical boring, or production focusing on reducing a reject rate.
In order to fix the spring element in a non-displaceable manner on the bolt, the bolt, according to a refinement, displays at least one offset, or an encircling cut-in, which axially fixes the spring element.
The spring element, on its inner and/or outer diameter, expediently displays a serration and is in particular designed so as to be cylindrical. The serration grips onto the respective component, wherein, on account of the comparatively small bearing face of the individual teeth, in the case of a correspondingly pre-tensioned assembly, high radial forces which counteract an axial extraction force, are effective.
Using the above-described connection means, the connection of two mutually abutting components is possible.
For example, angular components are coupleable to one another in a squarely abutting manner by means of at least one connection means, in that the connection means, with a first portion, under the effect of the spring element or spring elements of the first portion, is preferably inserted into a boring of the one component, and the other component is pushed onto the projecting second portion of the connection means until in particular the two components are connected so as to squarely abut against one another and, in the borings of the two components, spring elements of a connection element advantageously are effective against extraction forces.
The components may be any type of concrete components, in particular what are referred to as precast concrete parts, such as supports, beams, binders, facades, stairs, architraves, ceiling or wall slabs, or pillars. A
combination of these components with other components, for example of steel, in the form of angle sections, T-profiles or double-T--profiles, is also possible.
In an embodiment, at least one end side is provided with borings for the pre-tensioned accommodation of the at least one toothed spring disk of the connection means.
The borings may be introduced at the production site or at the construction site for example, by using a template, such that a uniform hole pattern is ensured in the components which are to be connected to one another.
The component preferably displays a plurality of borings which run across the longitudinal extent of said component and into which the free ends of the connection element protrude. The number of the connection elements to be mounted is substantially determined by means of the static requirements set for the connection.
In the sector of precast concrete part construction, components such as precast concrete parts are used and, in particular, concrete slabs which, on their abutting edges, display grooves and which, for connecting the precast concrete parts, are packed with concrete and, for absorbing tensile forces, are additionally equipped with anchors, screws, metal loops or brackets, are used for building support structures, facades, walls and/or ceilings.

The connection means 1 comprises a bolt 2 which comprises a plurality of spring elements 3, which are effective in opposite directions, in the form of resilient tongues 11 which, in the axial direction, are displaceable neither in relation to one another nor in relation to the bolt 2.
The orientation of the tongues 11 is determined in such a manner that they counteract an extraction force acting on the bolt 2.
For connecting two components 7 configured as precast concrete parts 6 so as to abut, borings 9, which display a diameter which is dimensioned so as to be smaller than the useable width of the bolt 2 having the spring elements 3 sticking out on the circumference, are introduced into the end sides 8 of the components 7, so that the tongues 11 are pressed into the borings 9 under pre-tensioning. For connecting two components 7, initially a plurality of connection means 1 are inserted into the corresponding borings 9 of the one component 7, and subsequently the next component 7 is pushed onto the free ends of the connection means 1.
In an alternative embodiment, the connection means 1 comprises the bolt 2 having the spring elements 3 in the form of toothed spring disks 4 which are serrated on the inside and the outside and which are axially fixed on the bolt 2, either in grooves and/or cut-ins 12 or by way of an offset 5, in such a manner that they are not displaceable in the axial direction in relation to one another and/or in relation to the bolt 2. The orientation of the toothed spring disks 4 is determined in such a manner that they counteract an extraction force acting on the bolt 2.
For connecting the components 7 so as to abut the borings 9, which display a diameter which is dimensioned so as to be smaller than the outer diameter of the toothed spring disks 4, are introduced into the end faces 8 of the components 7, so that the toothed spring disks 4 are pressed into the boring 9 during mounting. The connection means 1 are inserted into the corresponding boring 9 of the one component 7, and subsequently the next component 7 is pushed onto the free ends of the connection means 1 in such a manner that a toothed spring disk 4 of the connection means 1 is effective against extraction forces, even in the boring 9 of said component 7. The grooves 10 between the adjacent components 7, which are present in the end-side bearing region, may be packed with concrete. On account of the connection means 1 which are effective between two components 7, a coupling of the components 7 which withstands tensile forces is ensured.
In a further alternative embodiment, the connection means 1 is configured so as to be a type of nail and comprises the bolt 2, having the spring element 3, and an end-side head 13 having a diameter which is enlarged in relation to the bolt 2. According to the exemplary embodiments as per figs. 5 and 6, the one component 7 is implemented as a precast concrete part 6 and the other component 7 is implemented as a steel angle 14, wherein the connection means 1, with its bolt 2, protrudes through the boring 9 of the steel angle 14 and, by way of its spring element 3, is held in the boring 9 of the precast concrete part 6. The head 13 of the nail-type connection means 1 bears on the angle steel 14. As already explained, the spring element 3 is positioned in the axial direction either by way or an encircling cut-in 12 or by way of an offset 5.
The connection means 1 comprises a bolt 2 which comprises a plurality of spring elements 3, which are effective in opposite directions, in the form of resilient tongues 11 which, in the axial direction, are displaceable neither in relation to one another nor in relation to the bolt 2.
The orientation of the tongues 11 is determined in such a manner that they counteract an extraction force acting on the bolt 2.
For connecting two components 7 configured as precast concrete parts 6 so as to abut, borings 9, which display a diameter which is dimensioned so as to be smaller than the useable width of the bolt 2 having the spring elements 3 sticking out on the circumference, are introduced into the end sides 8 of the components 7, so that the tongues 11 are pressed into the borings 9 under pre-tensioning. For connecting two components 7, initially a plurality of connection means 1 are inserted into the corresponding borings 9 of the one component 7, and subsequently the next component 7 is pushed onto the free ends of the connection means 1.
In an alternative embodiment, the connection means 1 comprises the bolt 2 having the spring elements 3 in the form of toothed spring disks 4 which are serrated on the inside and the outside and which are axially fixed on the bolt 2, either in grooves and/or cut-ins 12 or by way of an offset 5, in such a manner that they are not displaceable in the axial direction in relation to one another and/or in relation to the bolt 2. The orientation of the toothed spring disks 4 is determined in such a manner that they counteract an extraction force acting on the bolt 2.
For connecting the components 7 so as to abut the borings 9, which display a diameter which is dimensioned so as to be smaller than the outer diameter of the toothed spring disks 4, are introduced into the end faces 8 of the components 7, so that the toothed spring disks 4 are pressed into the boring 9 during mounting.

The grooves 10 between the adjacent components 7, which are present in the end-side bearing region, may be packed with concrete. On account of the connection means 1 which are effective between two components 7, a coupling of the components 7 which withstands tensile forces is ensured.
In a further alternative embodiment, the connection means 1 is configured so as to be a type of nail and comprises the bolt 2, having the spring element 3, and an end-side head 13 having a diameter which is enlarged in relation to the bolt 2. According to the exemplary embodiments as per figs. 5 and 6, the one component 7 is implemented as a precast concrete part 6 and the other component 7 is implemented as a steel angle 14, wherein the connection means 1, with its bolt 2, protrudes through the boring 9 of the steel angle 14 and, by way of its spring element 3, is held in the boring 9 of the precast concrete part 6. The head 13 of the nail-type connection means 1 bears on the angle steel 14.
